Peter Mondavi, Napa Valley pioneer, dies at 101

Napa Valley wine pioneer Peter Mondavi, Sr., has died at the age of 101.

In 1943 Mondavi's parents bought the Charles Krug Winery, which was founded by Prussian emigrant Charles Krug in 1861, making it the oldest winery in Napa Valley.

Mondavi became CEO when his mother died in 1976. He acquired 800 acres to expand his vineyard on former dairy land. His winery became the first to import French oak barrels for aging, and he was among the first to plant pinot noir and chardonnay grapes in the region.

Mondavi helped change the reputation of Napa Valley into one of the world's leading wine making regions.
